Genetic default

Weird take but I've been arguing online as I sometimes always do, and the cognitive dissonance is so incredibly strong I'm literally at a shock point inside of myself. I'm seriously starting to wonder, and in no disrespect to people on this planet, but I think people who continue to believe in a deity from a book, Bible or Quran, that they might be genetically predisposed to whole heartedly accept whatever it is theyre told without question. Like, they are very much wired to want things a certain way and see things a certain way and somehow the Bible and the Quran seem to fit those dopamine and serotonin receptors in just the right way that no amount of reality will ever pull them out!
